Description
Lager üblicher Art bestehen aus mehreren kleinen Sphären oder zylindrischen Stahl-Einheiten, die in einem Gehäuse untergebracht sind. Das Gehäuse ist in der Regel ringförmig und in zwei Teile getrennt. Die kleinen Sphären oder anders geformte Konstruktions-Einheiten rotieren zwischen den Ringen und ermöglichen so das Drehen der Maschinen-Teile oder Räder mit sehr wenig Reibung. Diese Lager müssen ständig mit Schmierstoffen geschmiert werden, um die Reibung noch kleiner zu halten. Fehlt dieser oder ist zu lange im Gebrauch, tretten Probleme mit dem Lager auf, welche bis zur Zerstörung des Lagers führen können. Es gibt auch die sog. Luftlager, die zwar keine Schmierstoffe brauchen, aber ständig mit Luft aufgepumt werden muss.Common bearings consist of several small spheres or cylindrical steel units housed in a housing. The housing is usually ring-shaped and divided into two parts. The small spheres or other shaped structural units rotate between the rings, allowing the machine parts or wheels to rotate with very little friction. These bearings must be constantly lubricated with lubricants to keep friction even lower. If this is missing or is in use for too long, problems with the bearing arise which can even lead to the destruction of the bearing. There are also so-called air bearings, which do not require lubricants but must be constantly pumped up with air.
Der in den Schutzansprüchen 1 bis 12 angegebenen Erfindung liegt das Problem zugrunde ein Lager zu schaffen, das in der Lage ist, absolut ohne Schmierstoffe und Verschleissteile zu funktionieren.The invention specified in claims 1 to 12 is based on the problem of creating a bearing that is able to function absolutely without lubricants and wearing parts.
Dieses Problem wird mit den in den Schutzansprüchen 1 bis 12 aufgeführten Merkmalen gelöst.This problem is solved by the features set out in claims 1 to 12.
Vorteile der Erfindung sind:Advantages of the invention are:
- dieses Lager wird nie heiss,- this bearing never gets hot,
- braucht absolut keine Schmierstoffe,- requires absolutely no lubricants,
- ist total lautlos,- is totally silent,
- es ist sehr sauber,- it is very clean,
- enthält keine Verschleissteile,- contains no wearing parts,
- es funktioniert absolut Reibungslos etc.- it works absolutely smoothly etc.
Ausführungsbeispiele der Erfindung werden anhand der Figuren 1 bis 6 erläutert. Es zeigen:Embodiments of the invention are explained with reference to Figures 1 to 6. They show:
Fig. 1 das neuartige Lager,Fig. 1 the new bearing,
Fig. 2 die schematische Darstellung der Anordnung der Magnetischen-Domänen 4,Fig. 2 shows the schematic representation of the arrangement of the magnetic domains 4,
Fig. 3 eine Variante mit Doppelkonstruktion, Fig. 4 eine Variante mit magnetischer Nadel 7, Fig. 5 eine Variante, bei der eine Magnet-Scheibe in den Ring eingesteckt ist,Fig. 3 a variant with double construction, Fig. 4 a variant with magnetic needle 7, Fig. 5 a variant in which a magnetic disc is inserted into the ring,
Fig. 6 eine andere Variante mit Magnet-Scheibe.Fig. 6 another variant with magnetic disc.
In den Figuren ist der Magnetische Stator 1 und Rotor 2 dargestellt. Der Stator hat eine konvexe oder konkave Form, je nachdem, wie und wo er eingesetzt wird. Der Rotor hat die Gegenform (passende Form) des Stators.The figures show the magnetic stator 1 and rotor 2. The stator has a convex or concave shape, depending on how and where it is used. The rotor has the opposite shape (matching shape) of the stator.
Rotor und Stator sind an den Gelenkstellen 3 bzw. "Kontaktstellen" mit der gleichen Polarität magnetisiert. Die MikroStruktur des "Gelenks" besteht aus radial angeordneten Elementar-Magneten (Domänen) 4.The rotor and stator are magnetized with the same polarity at the joints 3 or "contact points". The microstructure of the "joint" consists of radially arranged elementary magnets (domains) 4.
Sie sind mit einer spezial Verfahren herzustellen.They are manufactured using a special process.
Durch einfachen Bohren des Magnets ist dieser Radial-Anordnungs-Effekt der Domänen 4 nicht zu erreichen.This radial arrangement effect of domains 4 cannot be achieved by simply drilling the magnet.
Die Magnetischen Abstosskräfte verteilen sich dadurch sehr homogen.The magnetic repulsion forces are therefore distributed very homogeneously.
Diese Kräfte üben eine Wirkung auf den Rotor des Lagers aus. Sie halten ihn schwebend in der Luft. Durch spezielle Verformung des Stators ist der Abstand zwischen den Magnetischen "Kontakt-Flächen" des Rotors und Stators stets nahezu konstant. Um eine bessere Balance zu erreichen, ist die Variante, die in Figure 3 dargestellt ist sehr gut geeignet. Sie besteht aus einer Doppelkonstruktion, die sich gegenseitig unterstützt. Die Kugelgelenke 3 erzeugen Magnetfelder, die eine stabile Distanz zwischen den Gelenk-Teilen ermöglichen. DerThese forces have an effect on the rotor of the bearing. They keep it floating in the air. Due to the special deformation of the stator, the distance between the magnetic "contact surfaces" of the rotor and stator is always almost constant. To achieve a better balance, the variant shown in Figure 3 is very suitable. It consists of a double construction that supports each other. The ball joints 3 generate magnetic fields that enable a stable distance between the joint parts. The
drehende Teil des Lagers, der Rotor, schwebt so frei in der Luft. Der Stator hält ihn mit Hilfe eines Magnetfeld in Schach. So kann der Rotor völlig reibungslos gedreht werden. An der Achse 5 kann ein Rad 6 oder Maschinenteil 8 befestigt werden.The rotating part of the bearing, the rotor, floats freely in the air. The stator keeps it in check with the help of a magnetic field. This allows the rotor to rotate completely smoothly. A wheel 6 or machine part 8 can be attached to the axle 5.
